TID hash joins are a simple and memory-efficient method for processing large join queries. They are based on standard hash join algorithms but only store TID/key pairs in the hash...
This paper argues that most queries in object-oriented databases require traversing from one object to another in the aggregation hierarchy. Thus, the connections between objects ...
We investigate the semantics for Knowledge Query Manipulation Language KQML and we propose a semantic framework for the language. KQML is a language and a protocol to support comm...
The rapid advances in computer and communication technologies, and their merger, is leading to a global information market place. It will consist of federations of very large numb...
Human Genome Project databases present a confluence of interesting database challenges: rapid schema and data evolution, complex data entry and constraint management, and the need...
